摘　　要：在分析美国BAR 97和我国在用车工况法排放检测有关标准中关于底盘测功机摩擦功率测试方法优缺点的基础上,提出适用于ASM稳态加载工况和IG195瞬态加载工况加载测试、恒加载滑行测试和变载荷滑行测试的摩擦功率测试的新方法,给出了计算公式。在某底盘测功机上的多次测试表明,该方法方便可行,摩擦功率计算更准确。Based on the analyses on the measuring schemes for parasitic losses of chassis dynamometer with BAR 97 in the US and the in-use vehicle emission test standards in China, a new measuring method for parasitic losses used in both constant load and variable load coasting down for both ASM and IG195 driving cycles is set up with calculation formulae given. The test results show that the new method is feasible, easy to use and more accurate in parasitic losses calculation.
